Re: I am not really assuming any discounts as the 3800+ price hit $300 on 1/23. I believe the averages are weighted heavily to the entry model of each range.
How heavily would you have to weigh a product mix without discounts before the average dips below the lower bound of the range?
I suppose you could make an argument that the product lines are bottom weighted, but if you show the work, I think you'll find it to be a highly unlikely scenario. In the Athlon 64 product line, for example, you are assuming a $160 average, but the product pricing starts at $155 for an Athlon 64 3200+ and goes up to $341 for an Athlon 64 4000+. You would have to assume a mix like this:
I think this is a lot more realistic, assuming list price. But I'll also agree that an 18% discount could bring these parts inline with a $160 ASP.
Re: As to the 73 vs the 85 that was modified in light of AMD's own data which showed some shifting from the 90% historical average which I had in mind before.
Well, I'm happy to have influenced you to go back and research AMD's own data.
Hopefully, your own work with a viable ASP scenario will help to change your opinion further.
